Definitions

  • the first user equipment 121 and the second user equipment 122 are located in a 20 cell 115 served by the network node 110.
  • the network node 110 may be referred to as a base station.
  • the network nodes 110 may e.g. be an eNB, an eNodeB, or a Home Node B, a Home eNode B, a femto Base Station (BS), a pico BS or any other network unit capable to serve a user equipment or a machine type communication device which are located in the cell 130 in the wireless telecommunications network 100.
  • the network node 25 110 may also be connected to a core network node (not shown) in the wireless
  • the transceiving unit 311 may also be configured to receive information about an adjustment of the transmit power of the beacon signal 140 from the network node 110. This reception is also performed prior to transmitting the beacon signal 140. This received information about an adjustment may then be used by the adjustment unit 312 when adjusting the transmit power of the transmit power of the beacon signal 140.
